Einul: I see where I have misled you.
You seem to be preoccupied with 10,000' above the ground.
You do not want to fly, in your case, up to 17,000' at 250 knots.
You care about 10.000 ft QNH, or QNE on the way down.
Yes, if you would take of at 7000', you might want to restrict your 250 kts a bit longer, so a manual entry would be required.
As quoted, LVL Change would be the easiest solotion.
